The Good Shadow Guard Who Came from the Tang Dynasty

In Li Zi's impression, time travel should not be about modern people traveling to ancient times, with a belly full of history books, golden fingers wide open, and living happily. But who can tell her what is going on with the shadow guard in front of her who came from the Tang Dynasty? He doesn't even know the basic common sense of life and has to teach him bit by bit from scratch. But since he is handsome, has a good figure, has a good temper, is good at martial arts and is obedient, I will reluctantly keep him.
